Size guide for Royal Mail letters & large letters

A tool for checking if your parcels/letters are a royal mail large letter or a normal letter!

Correct heights and widths!

I have found this very useful so far, so I know that my postage labels are always correct before going to the post office!

I also have a model on my profile with text on top to show the maximum dimensions!

I used esun PLA matte dark grey!

Let me know if you have any questions :)
